Parts for your 2018 Subaru Outback-Brake shoes

2018 Subaru Outback brake shoes: what they are and when they matter

Technical sources including the Subaru Service Manual for the 2015–2019 Outback (BS/BN platform, Brake > Parking Brake section) and Subaru genuine parts catalogues confirm the 2018 Subaru Outback uses brake shoes for the rear parking brake in a drum-in-hat arrangement inside the rear disc rotors. The service brakes are four-wheel discs with pads, while the brake shoes operate solely as a mechanically actuated parking brake.

On this Outback, the brake shoes sit inside the “hat” of the rear rotor and clamp against the internal drum when the handbrake is applied. Their job is to hold the vehicle steady during parking, hill starts, or when stopped with the transmission in Neutral. Because they aren’t used for normal stopping, they typically wear far more slowly than disc pads, but they still need periodic checks and proper adjustment to work reliably and to pass a WOF or roadworthy.

As part of routine servicing, workshops usually inspect and adjust the parking brake shoes whenever the rear rotors are off, or at set kilometre intervals. The Subaru manuals outline a star-wheel adjuster that sets the shoe-to-drum clearance. Too tight and the shoes can drag and overheat, too loose and the handbrake lever travel becomes excessive and holding power drops.

• Signs the brake shoes need attention:
  • Excessive handbrake lever travel or a spongy feel
  • Poor holding on hills or during a WOF/roadworthy test
  • Grinding, scraping, or a burning smell from the rear
  • Contamination with grease or brake fluid inside the rotor hat

• Good practice for replacement and maintenance:
  • Inspect lining thickness and shoe surface for glazing, cracking, or contamination
  • Clean the drum surface and hardware, replace return springs and clips if fatigued
  • Lightly lubricate backing plate contact points and the adjuster threads (never the friction surfaces)
  • Adjust to slight drag, then back off per service manual guidance, and bed-in with a few gentle parking-brake applications at low speed

Owners who keep the parking brake mechanism clean, correctly adjusted, and free of leaks can expect long service life from the 2018 Outback’s brake shoes. When in doubt, a technician should verify shoe thickness against the Subaru service limits and check that the lever travel and holding performance meet specification.

Popular questions about 2018 Subaru Outback brake shoes

Do 2018 Subaru Outbacks actually have brake shoes?

Yes. While the Outback runs disc pads for normal braking, it uses small drum-style brake shoes inside the rear rotors for the parking brake. This drum-in-hat setup is documented in Subaru’s service literature and parts diagrams for the 2018 model.

How often should the parking brake shoes be replaced?

They usually last a long time because they’re not used for everyday stopping. Most workshops inspect them whenever rear rotors are removed or roughly every 30,000–50,000 km, adjusting the star wheel as needed. Replacement is recommended if the linings are thin, glazed, cracked, contaminated, or if the adjuster is near its limit.

What symptoms point to worn or misadjusted brake shoes?

Excessive handbrake lever travel, poor hill-hold, scraping noises from the rear, or a burning smell after using the handbrake all suggest the shoes need inspection. A proper clean, adjustment, or shoe/hardware replacement typically restores solid holding performance.
